"Playa" in the dialect of hip-hop and rap means player, as in, the kind of person who "plays the field", thinks it is cool to flirt with everyone in sight, and go to bed with whoever, as long as she is (semi-)conscious, and thinks that monogamy is some kind of tropical disease. Most girls in my salsa community despise them whenever they actually take the time to consider them. Some guys think the title itself is a cool status symbol.
